ELECTR-IC PUMPING APPARATUS.

SPECIFICATION forming' part of Letters Patent No. 260,408, dated July 1882'.

Application inea August 29,1881. (No model.)

Our invention relates to anew system of and apparatus for pumping water or other liquids by electricity; and it consists, first, in the system of pumping by electricity in which the action or non-action of the electric apparatus is automatically controlled by the excess of supply of the liquid pumped over the demand for the same.

It further consists of an electric pump composed of a cylinder provided with. a valve near its upper end arranged to open upward, and two tubular pistons, each provided with a valve arranged to open upward, two electromagnets, each provided with a pivoted armature, the free or movable end of which is connected to one ot' said pistons in such a manner that the vibrations of said armatures will cause slaid pistons to reciprocate in the pump-cylin- I er.

lt further consists ot' a pump-cylinder provided with pistons and valves, two electromagnets, and two pivoted armatures, constructed and arranged as above described, all

' mounted upon a float in such a manner that said pump may rest upon the surface ot' the water or liquid to be pumped.

It further consists in the combination of the pumpcylinder provided with two pistons and v suitable valves, two electromagnets, two pivoted armatures connected by their free or Inovable ends with saidpistons, and means of -shunting a portion ot' the electric current when suitable valves, two electro-magnets, two piv- -oted armatures connected to and adapted to work said pistons, two shuntin g devices connecting with said armatures when closed, and a commutator arranged-to be operated by said shunted current and control the passage of the main current alternately through one and then the other ot' said electro-magnets or the coils thereof.

It lfurther consists in the combination of a batteny, an electrically-operated pump, a reservoir to receive the liquid pumped, a tloat in said reservoir arranged to rise and fall with the surface of the liquid contained therein,and intermediatemechanism between said tloat and the zines of the battery, so arranged and connected. therewith that a rise of the surface of the liquid in the reservoir to a given height will cause the zines to be removed from the acid in the battery, and a fall ofthe surface of said liquid to a certain lower level-will canse the zincs to be replaced in the acid.

Figure 1 of the drawings is a side elevation of our pump, drawn full size. Fig. 2 is a central vertical section of the same. Fig. 3 is a side elevation of the commutator, drawn to the same scale as the pump. Fig. 4 is a1 sectional elevation of the reservoir and oat and the lever operatedthereby, drawn to a reduced scale. Fig. 5 is a side elevation of the battery, drawn to the same scale as the reservoir; and Fig. 6iis a diagram 'showing the manner of connecting the several parts of the apparatus to make up a complete automatically-regulated pumping-machine.

A is the pump-cylinder, provided near its upper end with the upwardlyopening valve a and with the two hollow or tubular plnngers or pistons, B and B', each having tted to its upper end an upwardly-opening valve,vb or b', respectively. The cylinder A is rnily set in an upright position in the oat G, which is designed to rest upon the surface ot'. the water in the Well or other source of supply, as' shown in Fig. 6. The valves a, b, andb are pressed to their seats by spiral springs, as shown in Fig. 2.

Two slots, c and c', are cut through the wall of the cylinder A, upon opposite sides thereof and at different l'evels--thatis,at or near the centers of the lengths of the pistons B and B',

IOO

lengths relative to the lengths of said slots that said slots will always be covered by said pistous.

The pistons B and B' have set in their sides the studs d and d', respectively, which studs project horizontally therefrom through the slots c and c', to serve as a medium through which movement may be imparted to said pistons.

D is a two-armed bar provided with a socket at the center of its length, which embraces the cylinder A, to which it is secured in a fixed position by the set-screws, the two arms of said bar being located at different levels, and each having cast therewith and pendent therefrom two round pins or studs,f orf', to serve as cores to receive and support the coils g g and g' g', of insulated wire of large size, as shown. These coils g g and g' g', with the cores f and f', constitute two electro-magnets, E and E', respectively placed upon opposite sides of the cylinder A iu positions shown in Figs. 1 and 2.

The coresfand f' that are farthest from the cylinder A are made somewhat longer than their mates, and have pivoted thereto the armatures F and F', respectively, the inner or free ends of said armatures being forked and engaging respectivelyv with the studs d and d' of the pistons B and B'.

The inner poles or coresfand f' of the magnets E and E' have formed upon or secured to their lower ends the arms h and It', which project inward toward the cylinder A directly over and in line with the armatures F and F', respectively, and have secured thereto, butinsulated therefrom, the brass contact-pieces t' and i', respectively, with which the contactpieces j and j' respectively come in contact when said armatures are moved upward by the attraction of the electro-magnets E and E'.

Between the two coils of each magnet is arranged a spiral spring, 7c, the lower end ot' which is attached to the armature, and its upper end to the rod l, adjustably attached to the horizontal arm D, said spring k being so adjusted that it will tend to hold the armature in about the center of its vibratory movement when the pump is not in operation, and of such power or tension as to permit the armature to be moved upward by the attraction of the electro-magnet when the circuit is closed, while at the same time the reaction of said spring and the momentum of the descending armature will cause said armature to descend below the normal position, which it will finally assume it' the circuit remains broken.

The commutator shown in Fig. 3 consists of the base G, of wood or other non-conducting material, upon which are mounted the two electro-magnets H and H', insulated from each other, butin metallic connection with the screwcups m and m', respectively.

Centrally located between the two magnets H and H' is the` metallic post or standard l, to the upper end of which is pivoted the brass rocking lever J, to the opposite ends of which are secured, in positions at right angle thereto,

the soft-iron armatures a and a' directly above the cores of the magnets H and H', respectively.

The rocking lever J is provided with a third arm, J', arranged atright angles to the main lever and projecting downward therefrom, to the lower end of which is pivoted the short stud o, around which the upper end of the spring p is coiled, the lower end of said spring being in like manner coiled around a similar stud, o', which is pivoted to the standard I.

The oiiice ot' the arm J' and the pivoted spring-connection op o'is to hold the rocking beam or lever J in a tilted position, with the armature at its lowest end in contact with its magnet till said lever is tilted in the opposite direction by magnetizing the cores of the opposite magnet and the demagnetizing otl the ycores with which the armature is then in contact. This is an important feature of our nvention.

The upper end of the pump-cylinder A is connected by the flexible pipe q to the lixed pipe q', which leads to and discharges into the reservoir-tank K, in which is placed a doat, L, from the upper side of which rises the rod r, the upper end of which is connected, through the medium of the slot 1^' and the pin r2, with the short arm s of the lever M, pivoted at s' to the stand M', and having secured to the free or movable end of the arm s2 the cord t, the opposite end of which is made fast to thc periphery of the pulley O on the drum-shaft O', located above the battery cells or cups P P, and having its bearings in the upper ends of the uprights Q Q'.

R 1t' are guiding-pulleys for directing the cord t in the right path.

The zines and carbons of the battery are suspended from a suitable frame, S, which extends across and rests upon the tops of the cups P P, and is provided at its ends with eyes which embrace the rods Q and Q'.

T T are two cords secured by one end to the drum O2, and wound several times around said drum, and secured at their other ends to the frame S in such a manner that by rotating thedrum O2 said frame and the zincs and carbons attached thereto may be raised, so as to remove the zincs and carbons out ot' the acid, or lowered to insert them again in the acid. The cord tis wound several timesaround the pulley O, so that a draft upon said cord to unwind it from said pulley will cause the drum 02 to be rotated so as to wind up the cords T T upon said drum, and thus raise the frame S. The lever M is provided with a third arm, s3, arranged at right angles to the arins s and s2 and radial to the axis ot' vibration of said lever, and the arms s2 and s3 have mounted thereon the adjustable weights U and U', respectively, the weight U being so adjusted on the arm s2 as to just counterbalance the weight of the frame S, with the zincs and carbons at tached thereto.

The method of connecting the several parts of the apparatus is clearly shown in Fig. 6,

where it will be seen that one terminal of each pump-magnet is connected with one pole-say negativeof the battery by the wires u and u',

, and the same pole is also connected with the frame of the pump by the wire u2.

The other terminals of the pump-magnets are connected one to the screw-cup m and the other to the screw-cup m' of the commutator by the wires a3 and u* respectively.

The positive pole'ot' the battery is connected by the wire a5 to the standard I of the commutator, and one terminal ot' each of the commutator-magnets H and H' is in like manner connected to the-standard I, and the other terminals of said magnets are connected respectively, by the wires as and-a7, to the contactpieces 'i' and t', or the nuts by which said contact-pieces are secured in place.

The operation of our invention is as follows: The several parts of the apparatus being counected and placed in position, as shown in Fig. 6, and the battery being properly charged, the electric current will pass from the battery, through wire u, coils g g ot' magnet E, wire a3, to screw-cup in, thence to the cores of magnet H, through said cores, through the armature n, lever J, standard I, and wire a5 to the battery. The magnetized cores ofthe magnet E attract the armature, causing itsinner or free end to move upward, carrying with it the piston B, which causes the valve a to be raised to permit the discharge ot' a portion ot' water or air that may be above said piston. When the armature F comes in contact with the contactpiece fi a shunt or branch circuit is completed, so that a portion ot the electricity will pass through wire u2, the frame of the pump-armature F, contact-piece t', wire u", through the coils of the magnet H', to the standard I, where it unites again with the main circuit. The induced magnetism of the magnet II' attracts its karmature u with sufficient force to overcome the tension of thespring p and tilt the lever J to the opposi-te angle t rom that shown in the drawings, thus breaking the circuit through the magnet and closing a new circuit,

Vin which is included the magnet E, the armature F' having previously fallen away from said magnet to a position corresponding to that of armature F in the drawings. The magnetism induced in the co1 es of the magnet E by the passage of the current of electricity through the coils g' g' of said magnet attracts the armature F', causing its inner or free end to move upward, carrying with it the piston B', at the same time that the armatureF and piston B descend, which movements of the pistons B and B cause the valve b to open upward and a given quantity of water to pass through it to the chamber above, and at the same time the valve a is opened upward and a quantity of water equal to one-halt' that delivered through the valve b is discharged through the valve ot into the pipe q. The completion of the upward stroke ot' the armature F closes the shunt or branch circuit through wire u", pump-frame, armature F', contactpoint fi', wire a6, the coils of the magnet H to the standard I,where it unites again with the main circuit. The circuit through the magnet H having been previously broken by thepfalling away of the armature F, caused by the breaking ot the circuit through the magnet E, the lever J will be again tilted to the position shown in the drawings by the attraction of the armature n by the magnet H, thus causing a breaking otl the circuit through the magnet E' and closing that through the magnet E. These operations will continue so long as the battery remainsoperative,the main circuits being alternately changed from the magnet E to magnet E', and vice versa, and the shunt-circuit being alternately changed from magnet H' to magnet H, and vice versa, and as a consequence thereof` the pistons B and B' making alternate reeiprocations. The water is discharged through the pipes q and q' into the reservoir K, from which the supply for use is drawn. When the water has risen in the reservoir to the level shown in Fig. 6 the iioat L will have been lifted from its seat and moved upward, and will continue to so move upward, it' the water continues to rise in the reservoir, till the lower end ofthe slot r' has engaged with the pin r2 and moved the lever M around its axis of motion a distance sufficient to throw the center of gravity of the weight U' tothe opposite side of a line drawn perpendicularly through the pivotal axis of the lever M, when the preponderance of weight upon that side will cause the lever M to tilt to the position shown in dotted lines, the pin r2 moving in the slot r and the cord t being drawn over the pulleys R R' and unwound from the pulley O, thus causing the drum O2 to be revolved in such a manner as to wind upon it the cords T T and raise the frame S sufficiently to lift the zines and' carbons out ofthe acid, and thus stop the pump by checking the production of the motive power. As the water is drawn from the reservoir thefloat will descend with the fall of the water therein, and, overcoming the gravity of the weights U and U', moves the lever M around its pivot till the weight U' has passed to the right of the perpendicular linew,when the preponderance of weight upon that side will cause the lever M to be suddenly tilted to the position shown in full lines, and thus cause the zines and carbons to descend into the acids contained in the battery-cups P P, when the pump will be again set in operation.

The battery usedis a zinc-carbon one worked by a solution of bichromate of potash and sulphuric acid, said battery being of low resistance, andthe wire of the pump magnet-coils will be large to correspond, and we prefer to use for said coils Finleys patent rubber-coated wire.

The wire of the commutator magnet-coils will be quite tine, so that but avery smallpart of the current will be shunted through the commutator, as only a slightforce is needed totilt the com mutator-lever.
